BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an article inspection apparatus according to an
embodiment of the present invention will be described in detail
with reference to the drawings.
An article inspection apparatus 1 according to an embodiment of the
present invention is incorporated in a product line (not shown) on
which inspection objects W such as raw meat, fish, processed food,
medicine or the like are conveyed, and inspects foreign matters,
defects, or the like mixed in the inspection objects W, or whether
or not the weights of the inspection objects W are within a
specified range.
In FIG. 1, the article inspection apparatus 1 according to an
embodiment of the present invention includes a conveyance unit 2,
an inspection unit 3, a display operation unit 4, a determination
unit 5, an integrated control unit 6, and an inspection record
information accumulation unit 9.
The conveyance unit 2 sequentially conveys inspection objects W of
a type, which is previously set in the display operation unit 4,
from among various types such as raw meat, fish, processed food,
medicine or the like, for example, and is a belt conveyor disposed
horizontally to the apparatus body, for example.
Further, the conveyance unit 2 is driven by a driving motor (not
shown), and conveys the loaded inspection object W in the arrow
direction (rightward direction) in FIG. 1 at a predetermined
conveyance speed.
The inspection unit 3 is configured to output a detection signal
corresponding to the type and size of a foreign matter contained in
the inspection object W or a detection signal corresponding to the
weight of the inspection object W as a signal representing the
quality state of the inspection object W. In a case where the
article inspection apparatus 1 is a metal detection apparatus, the
inspection unit 3 is configured to generate an alternating magnetic
field of a predetermined frequency, and output a signal of which
amplitude and phase change corresponding to the change of the
magnetic field caused by the inspection object W passing through
the alternating magnetic field. It may also be configured to
magnetize the metal contained in the inspection object W with a
magnetizer such as a magnet and to detect the residual magnetism of
magnetized metal with the magnetic sensor.
In a case where the article inspection apparatus 1 is an X-ray
inspection apparatus, the inspection unit 3 includes an X-ray
generation source and an X-ray detector, and the X-ray detector is
configured to detect X-rays transmitted through the inspection
object W, when the X-ray is emitted from the X-ray generation
source, and output a detection signal corresponding to the amount
of transmission. As the X-ray detector, for example, an array-like
line sensor including a plurality of photodiodes arranged in a line
shape in a direction orthogonal to the conveyance direction of the
inspection object W conveyed by the conveyance unit 2 and a
scintillator provided on the photodiode is used. The X-ray detector
is configured to receive X-rays transmitted through the inspection
object W by a scintillator, convert the received X-rays into light,
convert the light into an electric signal by a photodiode disposed
below the X-ray detector, and output the electric signal. That is,
an electric signal corresponding to the amount of X-ray
transmission is output.
In a case where the article inspection apparatus 1 is a weight
measurement apparatus, the inspection unit 3 is configured to use a
part of the conveyance unit 2 is a weighting platform, weigh the
load of the inspection object W placed on the weighing platform, by
a load sensor including a balance mechanism such as an
electromagnetic balance mechanism, which is disposed under the
weighting platform, and outputs a signal corresponding to the load.
The load sensor may be any scale mechanism capable of measuring the
weight, and may be, for example, a scale mechanism such as a
differential transformer mechanism or a strain gauge mechanism.
On the upstream side of the inspection unit 3, a load sensor 52 for
detecting passage of the inspection object W conveyed by the
conveyance unit 2 is provided. The load sensor 52 is a
transmission-type photoelectric sensor including a pair of light
projection units and light reception unit (not shown) which are
disposed to face each other so as to straddle the conveyance unit 2
in the width direction (the front side and the back side in FIG.
1). When the inspection object W passes between the light
projection unit and the light reception unit, the light reception
unit is shielded by the inspection object W, so the load sensor 52
detects that the inspection object W passes through and loading of
the inspection object W in the inspection unit 3 is started. The
detection signal from the load sensor 52 is output to the control
unit 8.
The display operation unit 4 is a touch panel that also serves as
an input operation function and a display function, and is
configured to receive, as input operations, a setting operation of
the type of the inspection object W conveyed by the conveyance unit
2, and various setting operations and instruction operations
related to foreign matter detection, weighing and operation
confirmation with respect to the inspection object W.
As the display function, the display operation unit 4 is configured
to perform various types of display such as a setting value when
the setting operation of the type of the inspection object W is
performed, an instruction value when the instruction operation is
performed, various determination results, and the like.
The display operation unit 4 may have a configuration in which the
input operation function and the display function are independent.
In this case, a plurality of keys, switches, and the like for
receiving input operations such as setting and instructions can be
provided for the input operation function, and a liquid crystal
display or the like can be provided for the display function.
The determination unit 5 is configured to perform a pass/fail
determination as to whether or not a foreign matter is contained in
the inspection object W, whether or not the weight of the
inspection object W is within a specified range, or the like, based
on the detection signal from the inspection unit 3, and display a
screen including the determination result on the display operation
unit 4.
The integrated control unit 6 controls the whole of the article
inspection apparatus 1, and includes a storage unit 7 and a control
unit 8.
The storage unit 7 is configured to store various programs for the
control unit 8 to control the article inspection apparatus 1,
various parameters for the determination unit 5 to perform a
pass/fail determination on the inspection object W, and the
like.
The control unit 8 executes the program stored in the storage unit
7 to change parameters of the determination unit 5, and perform
various controls of the article inspection device 1, and the
like.
The control unit 8 stores the determination result by the
determination unit 5 for each inspection object W, a part of the
detection signal from the inspection unit 3 as the basis of the
determination result, and the date and time when the inspection is
performed, in the inspection record information accumulation unit
9.
That is, in the article inspection apparatus 1, the detection
signal from the inspection unit 3 is not discarded even after the
determination by the determination unit 5, and is accumulated in
the inspection record information accumulation unit 9. Further, the
detection signal from the inspection unit 3 is made to correspond
to each inspection object W according to the date and time when the
inspection is performed by the inspection unit 3 (or the
determination by the determination unit 5).
In this manner, the inspection record information accumulation unit
9 is configured to record all data of so-called inspection
results.
The control unit 8 searches for the inspection data stored in the
inspection record information accumulation unit by condition
setting by the operation on the display operation unit 4 and
displays the searched inspection data on the display operation unit
4.
For example, when the "today's NG list" of the article inspection
apparatus 1 as the X-ray inspection apparatus is input as an
extraction condition by the operation on the display operation unit
4, as shown in FIG. 2, the control unit 8 displays a list of the
inspection objects W determined to be defective items in the
inspection performed by the article inspection apparatus 1 as the
X-ray inspection apparatus on the day, on the display operation
unit 4.
In FIG. 2, for example, when the line indicated by A is selected by
the operation of the display operation unit 4, the control unit 8
displays the X-ray transmission image of the inspection object W
corresponding to the selected line on the image display unit
101.
In FIG. 2, for example, when a front/rear information display
button 102 is selected by the operation of the display operation
unit 4 in a state where the line indicated by A is selected by the
operation of the display operation unit 4, the control unit 8
displays a list of the inspection objects W produced and inspected
before and after the inspection object W of the line indicated by A
on the display operation unit 4 as shown in FIG. 3.
In FIG. 3, for example, when lines before and after the line
indicated by A are selected by the operation on the display
operation unit 4, the control unit 8 displays X-ray transmission
images of the inspection objects W corresponding to the selected
lines on the image display unit 101.
In this manner, a list of the inspection objects W produced and
inspected before and after the inspection object W which is
determined to be NG in the inspection is displayed, and the
inspection data can be selected and referred to by the operation of
the display operation unit 4.
For example, when a blade or the like is missing and mixed in a
product, large fragments are detected to make the result NG, but
small fragments are not detected to make the result OK, in some
cases. In such a case, there is a high possibility that small
fragments are mixed in the inspection objects W before and after
the inspection object W for which large fragments are detected and
is determined to be NG.
According to the present embodiment, by the operation of the
front/rear information display button 102, a list of the inspection
objects W before and after the inspection object W which is
determined to be NG is displayed and the inspection data can be
referred to, so it is possible to display the inspection
information of products which are inspected at the same time with
the defective inspection object W and are considered to require
confirmation, without resetting a search condition.
In FIG. 3, when the search result return button 103 is selected by
the operation of the display operation unit 4, the control unit 8
displays a search result screen as shown in FIG. 2, on the display
operation unit 4.
In addition, as shown in FIG. 4, a list of X-ray transmission
images of the inspection object W may be displayed as the display
screen of the search result. FIG. 4 shows a case where a list of
the inspection objects W determined to be defective items is
displayed.
In FIG. 4, when the image indicated by B is selected by the
operation of the display operation unit 4, the control unit 8
displays a list of the inspection objects W produced and inspected
before and after the inspection object W of the image indicated by
B on the display operation unit 4 as shown in FIG. 5. In FIG. 5,
the X-ray transmission images of respective seven inspection
objects W before and after the inspection object W of the image
indicated by B are displayed.
The X-ray inspection images of the same number of precedent and
subsequent inspection objects W may not be displayed respectively.
Alternatively, seven objects before and five objects after may be
displayed as shown in FIG. 6, or ten objects after may be displayed
as shown in FIG. 7.
In a case where the article inspection apparatus 1 is an X-ray
inspection apparatus, with respect to the images displayed on the
image display unit 101 and the images at the time of displaying a
list of the images of FIG. 4 to FIG. 7, the X-ray transmission
image as shown in FIG. 8A is displayed.
In a case where the article inspection apparatus 1 is a metal
detection apparatus, a Lissajous waveform generated from changes in
amplitude and phase of a signal output from the inspection unit 3
with time as shown in FIG. 8C is displayed.
In a case where the article inspection apparatus 1 is a weight
measurement apparatus, an image representing a change in weight
with time as a waveform as shown in FIG. 8B is displayed. The
inspection object W is weighed at a timing when the weight signal
by the inspection unit 3 is stabilized (timing sandwiched by two
broken lines in FIG. 8B).
Further, a list of the inspection objects W before and after the
inspection object W selected from the list of the inspection
objects W determined to be defective items is displayed. However,
when "today's NG list" is selected as the extraction condition, a
list of the inspection objects W before and after the latest
inspection object W determined to be a defective item may be
displayed.
Further, it may also be configured to be able to read the
inspection data stored in the inspection record information
accumulation unit 9 from a server apparatus or the like through a
communication medium such as a network, and the same display may be
performed by the server apparatus or the like.
Thus, various processes can be performed at a higher speed as
compared with the case where the control unit 8 performs the search
and data processing.
Further, inspection data may be transmitted to a server apparatus
or the like through a communication medium such as a network, the
server apparatus or the like may accumulate inspection data, and a
similar display may be performed by executing the program stored in
the server apparatus or the like.
This makes it possible to store a large amount of inspection data
as compared with the case of storing inspection data in the
inspection record information accumulation unit 9. Further, various
processes can be performed at a higher speed as compared with the
case where the control unit 8 performs the search and data
processing.
Further, inspection data of a plurality of article inspection
apparatuses may be transmitted to one server apparatus and managed
by the server apparatus.
Thereby, the inspection data of the plurality of article inspection
apparatuses can be referred to by one server apparatus, and
inspection data can be efficiently confirmed.
Although embodiments of the present invention have been disclosed,
it will be apparent to those skilled in the art that modifications
may be made without departing from the scope of the invention. All
such modifications and equivalents are intended to be included in
the following claims.
